ZEBRA PRINTER USB COMMUNICATIONS STOPS AFTER COMPUTER SLEEP CYCLE

DETAILS

Windows Print Queue fails to respond to a print request after a Computer Sleep and Wake up cycle

Labels in the print queue are not printing after sleep cycle

Applies To

Zebra Printer connected via USB to a Windows 7 or later operating system

Details

After a computer sleep and wakes up cycle a USB connected printer may not respond to new print request resulting in the print jobs remaining in the Windows Spooler.

In previous versions of Windows operating system the USB printing resumed after sleep mode. The USB host controller would automatically reset to thereby re-initialize all USB communications.

In Windows Vista version, the USB stack behavior was changed and did not execute, in most cases, a USB bus reset on system resume. In Windows 7, USB bus will not reset when the system resumes from sleep mode unless the attached USB device lost power during sleep cycle. As the USB communications are not re-initialized, the print job in the Windows spooler will not able to be routed properly to the printer.

Resolution:

Windows 7

1. Disable the "USB Charging" and "USB Wake up" options in BIOS.

2. Install the latest updates for Windows and install the latest drivers for the USB device.

(If you are using a USB hub, try to use the device without the hub.)

3. If the USB device is connected to a USB port on a portable computer docking station, try to connect the device directly to the USB port on the portable computer.

4. Disable the "USB selective suspends settings" option in the Power Options.

5. Disable the "Allow the computer to turn off this device to save power" setting in Device Manager. You may see multiple listings for USB Root Hub, uncheck this option for all USB Root Hubs.

Windows 8.1 Windows 10
